Rehabilitation of the edentulous maxilla complicated by combination syndrome with an implant overdenture: a case report.

The treatment of the edentulous jaws with complete dentures is determined individually and often is unpredictable. Implant-assisted overdentures are a significant improvement over conventional complete dentures in terms of patient comfort and function. Combination syndrome refers to a dramatic exaggeration of maxillary alveolar resorption leading to a more complicated rehabilitation. This article reviews how the edentulous maxilla can be rehabilitated with an implant-assisted overdenture. A case report is presented which utilizes a computer-aided design/computer-aided manufactured milled titanium connecting bar to retain a chrome-cobalt based, precision attachment, palateless prosthesis.
